In addition to those issues,stanc errors during $compile() are now thrown immediately with the stanc error message attached, instead of returning NULL and failing later

$compile(), $check_syntax() and $format() each turned stanc_options into
command line arguments with their own near-identical loop, and the three
had drifted apart: only $format() guarded against numeric values being
collapsed to a valueless flag. Replace all three with a single
stanc_options_to_args(), which takes a quote_values argument for the Make
path so the direct and Make-quoted forms stay in one place.

Boolean options are now keyed off is.logical() rather than
isTRUE(as.logical(value)). TRUE still emits a bare flag, FALSE now omits
the flag instead of emitting an invalid --flag=FALSE, and numeric values
are passed through as --name=value. Values spelled as the strings "TRUE"
and "FALSE" are no longer treated as flags.

$format() also assigned into stanc_options with [ rather than [[, which
coerced every element to a common type and so turned the logical TRUE for
auto-format into the string "TRUE". The old as.logical() coercion hid
this; assigning into a list keeps the types intact.

Drop the manual stanc_options = list("allow-undefined") from the
cpp_options user header test, which was masking the allow-undefined fix
and left that path without real coverage.
